Node Labels
HPE Ezmeral Data Fabric on Kubernetes nodeservice
pods create labels
on each node of the Kubernetes cluster.
Node Labels
The bootstrapping process deploys nodeservice
pods to
the hpe-nodesvc
namespace as a daemonSet. The nodeservice
pods create the following labels on each node of the Kubernetes cluster:
hpe.com/compute
- Whether (true; default) or not (false) to use the node for compute engines.false
is a weak scheduler hint that is ignored if there is no other place to store pods.hpe.com/exclusivecluster
- Storage cluster for which to use the node. Value can benone
(default; uses the node for any storage cluster pod in the Kubernetes environment) or<storage-cluster-name>
(only use the node for pods in the specified storage cluster).hpe.com/dataplatform
- Whether (true
; default) or not (false
) to use the node for storage cluster pods.false
is a weak scheduler hint that is ignored if there is no other place to store pods.hpe.com/usenode
- Whether (true
; default) or not (false
) to use the node for installing the storage cluster or running compute engines. Ifusenode
istrue
and bothcompute
anddataplatform
arefalse
, then neither storage services nor compute spaces are installed on the node; however, the node might be used when there are capacity issues.
The nodeservice
pods create the following annotations on
each node of the Kubernetes cluster:
-
hpe.com/status
-
hpe.com/createdpvs
-True
/False
- Internal use only. Flags the creation of persistent volumes. -
hpe.com/decommission
-Yes
/No
- Unused. -
hpe.com/validationversion
- Bootstrap utility version last run in the environment. -
hpe.com/fulldisklist
- Complete list of available and used disks detected on the node, including the disk size. -
hpe.com/hddlist
- List of available HDDs on the node.hpe.com/maintenance
-Yes
/No
- Unused. -
hpe.com/modifypvs
-Yes
/No
- Unused. -
hpe.com/nodetopology
- Node topology, in the format/<racknumber>/<nodename>
. Default israck1
. -
hpe.com/nvmelist
- List of available NVMEs on the node. -
hpe.com/physicalnodeid
- Example:51ee6ec19ac3af40
. -
hpe.com/rack
- Rack number label. Default israck1
. -
hpe.com/sddlist
- List of available SDDs on the node. -
hpe.com/validationerrors
- Whether (errors) or not (none) errors occurred during node validation. -
hpe.com/validationstatus
- Status of the validation operation. Value can be either validated (completed successfully) or validating (operation currently running). Do not modify this property. -
hpe.com/validationtimestamp
- Unused.
